Crankshaft Dej iav Investment Casting

Khoom Taw Qhia

Qhov tseem ceeb tshaj plaws nyob rau hauv lub engine. Nws siv lub zog los ntawm kev sib txuas ntawm tus pas nrig thiab hloov mus rau hauv lub zog, uas yog tso tawm los ntawm crankshaft thiab tsav lwm yam khoom siv ntawm lub cav ua haujlwm. Lub crankshaft yog raug rau kev sib xyaw ua ke ntawm lub zog centrifugal ntawm lub zog rotating, roj inertia quab yuam ntawm lub sij hawm hloov pauv thiab lub zog reciprocating inertial, yog li ntawd lub crank bearing yog raug khoov torsional load. Yog li ntawd, Crankshaft Water Glass Investment Casting yuav tsum muaj lub zog txaus thiab rigidity, thiab cov ntawv xov xwm saum npoo yuav tsum hnav-tiv taus, zoo ib yam thiab sib npaug.
Yuav kom txo tau qhov loj ntawm lub crankshaft thiab lub zog centrifugal generated thaum lub sij hawm txav, cov ntawv xov xwm crankshaft feem ntau ua hollow. Cov roj qhov yog ua rau ntawm txhua qhov chaw sau ntawv tso cai rau cov roj nkag los yog tshem tawm kom lubricate cov ntawv xov xwm nto. Txhawm rau txo qhov kev ntxhov siab, kev sib txuas ntawm cov ntawv xov xwm tseem ceeb, tus pin crank thiab crank caj npab yog txuas los ntawm kev hloov pauv arc.
Lub luag hauj lwm ntawm lub crankshaft counterweight (tseem hu ua counterweight) yog kom sib npaug lub zog centrifugal rotational thiab nws lub sijhawm, thiab qee zaum lub zog reciprocating inertia thiab nws lub sijhawm. Thaum cov quab yuam thiab lub sij hawm nyob rau hauv qhov sib npaug ntawm lawv tus kheej, lub counterweight kuj siv tau los txo cov load ntawm lub ntsiab bearing. Tus naj npawb, qhov loj thiab qhov chaw ntawm lub qhov hnyav yuav tsum raug txiav txim siab raws li tus naj npawb ntawm lub tog raj kheej ntawm lub cav, kev npaj ntawm lub tog raj kheej thiab cov duab ntawm lub crankshaft. Lub counterweight feem ntau cam khwb cia los yog forged nrog lub crankshaft, thiab counterweight ntawm high-power diesel xyaw yog tsim los ntawm lub crankshaft thiab ces bolted ua ke.
 

Casting Technology
• Smelting
Kev nrhiav tau ntawm high-temperature thiab low-sulfur pure molten iron yog tus yuam sij rau kev tsim cov hlau zoo. Hauv Suav teb, cov cuab yeej tsim khoom yog tsim los ntawm cupola rauv, thiab cov hlau molten tsis tau ua ntej desulfurized, ua raws li qhov tsis muaj cov npua hlau tsis zoo thiab cov coke tsis zoo. Cov hlau molten yog yaj nyob rau hauv lub cubola cub tawg, desulfurized sab nraum lub cub tawg, thiab ces rhuab thiab kho nyob rau hauv ib tug induction rauv. Hauv Suav teb, kev tshawb pom ntawm cov hlau molten muaj pes tsawg leeg tau dav ua los ntawm lub tshuab nqus tsev nyeem ntawv spectrometer.
• Kev ua qauv
Cov txheej txheem airflow feem ntau yog qhov zoo dua li cov av nplaum xuab zeb moulding txheej txheem, uas tuaj yeem tau txais kev ua haujlwm siab crankshaft castings, thiab cov xuab zeb pwm tsim los ntawm cov txheej txheem no muaj cov yam ntxwv ntawm tsis muaj rebound deformation, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau ntau tig crankshafts. Muaj qee lub tuam txhab hauv tsev crankshaft los ntawm lub teb chaws Yelemees, Ltalis, Spain thiab lwm lub teb chaws los qhia txog huab cua cuam tshuam cov txheej txheem molding, txawm li cas los xij, tsuas yog ob peb lub tuam txhab tau qhia tag nrho cov kab ntau lawm.
• Electroslag casting
Electroslag remelting thev naus laus zis yog siv rau kev tsim cov crankshafts, yog li ntawd qhov kev ua tau zoo ntawm cam khwb cia crankshafts yuav piv rau kev ua haujlwm forging. Thiab nws muaj cov yam ntxwv ntawm kev ceev R & D voj voog, kev siv hlau siab, cov khoom siv yooj yim thiab cov khoom ua tau zoo dua.
